Title:
PASSIVE CIRCUIT IN RADIO FREQUENCY RECEIVING MODULE BYPASS MODE, AND RADIO FREQUENCY RECEIVING MODULE
Document Type and Number:
WIPO Patent Application WO/2024/099060
Kind Code:
A1
Abstract:
The present application discloses a passive circuit in a radio frequency receiving module passive mode. The passive circuit comprises: successively connected, a signal input end, an amplification unit, an output matching circuit, and a signal output end; the passive circuit further comprises an attenuation circuit connected between an input end of the amplification unit and an input end of the output matching circuit; the attenuation circuit comprises a first transistor, a first path, a second path, a third path, and a second transistor; when the passive circuit is in a radio frequency receiving module bypass mode, signals received by the signal input end are attenuated to different degrees by means of the attenuation circuit and are then outputted to the input end of the output matching circuit. In the present application, the passive circuit in the radio frequency receiving module bypass mode achieves the function of attenuating high-power signals, and is further able to cause high-power signals to be attenuated to a required power signal to be outputted to a next-stage circuit.
